Maybe - it seems they are essentially the same with the N3207 adding the AC output required by the N2003 LBCD. But there's no guarantee that the lack of that input on pin F will still allow the regulator to properly function. It uses a different Amphenol connector to the alternator so that would...

It seems like this is a recurrent problem regardless of MV or not. Trucks be slow under some circumstances. Cars be fast with idiots behind the wheel - till we make every vehicle autonomous there will be collisions between the two. Such is life and risks are part of life. Personally I would...

I drove 2800 miles of almost entirely interstate at 50 and probably pissed off more than a few truckers wanting to go 80 on the flat and level - only to pass them at the same 50 going up the next mountain grade while they are doing 25-35. I would say I am decidedly less of a road hazard than a...

I drove 2800 miles from Houston to Portland at 50 mph and had no issues. I wasn't driving significant number of hours at night.

Excellent advice. Thank you.

I also hope I never have to do this. It sounds extremely inconvenient. I don't think it would be life changing for me - I've seen senseless death in combat and personally I've made my peace with it. Can't be worse than someone I know and have a personal attachment to. Some random motorist...... 😑

I hope the trailer was OK. What even WAS that car? Looks like it went under :tank:

And after you run those voltages through the PPD/LBCD the diodes drop the voltage another 0.7v so what you see at the PDP is about 27.5v and 13.4v. Which is really fine as everything computer-wise has to run on 10v or even lower during cranking. The batteries see 28 and 14 not being on the load...

World is over-populated and if the kid hits a truck as large as mine because I was 5 mph under the speed limit (like many a semi-truck on a grade) then Darwin got that fool and it was bound to happen anyway. I'll call emergency services and render aid as appropriate but I'm not going to lose...

That would take quite the idiot but I'm waiting for such an encounter. That pintle will be a real funny lookin stereo.

You will find the fuel economy significantly improved at 50 rather than close to 60 on stock gearing. The difference is about 2.5 mpg. With these trucks only getting around 8 that 2.5 matters a lot.

LBCD was replaced - had blown capacitors and a loose stud in addition to very nasty connections. That was replaced a while ago and I have since upgraded the battery disconnect relay to the current Cooper-Bussman fully enclosed unit and it works correctly using the toggle switch in the cab as...

Replaced all the battery cables today along with new terminal covers (several terminals were crushed and one had a crack (PVT Snuffy had wrecked them) and installed a brand new voltage regulator from 2018 to rule out the last few questions. So far I've not experienced any behavioral issues on my...

It's not impossible for the LED's in the regulator to have failed or part of the circuit that drives them - do you have another regulator from your old unit to try? Those voltages are good - you will have about a 0.70v drop across the polarity protection device so that's exactly what you want to...

In the Niehoff troubleshooting for the N1224-1 (https://www.ceniehoff.com/Documents/Ctrl_Hyperlink/TG0045A_uid12172009146362.pdf), it has this schematic: The Field in this design has a constant ground inside the alternator chassis and terminal A on the regulator harness is labeled "F+" and is...

Well I spoke with an engineer at Niehoff (amazing what a few phone calls will get you), and the brushless design of their alternators lends itself to quite a bit more AC ripple than a typical alternator design and they consider ripple up to +/-2v to be normal - so my readings don't indicate an...

I would drive it. But that's me. I caught a flight and drove my truck with a friend back 2700 miles.

Update: Have never quite resolved all the "weirdness" of my charging system. The alt will at times shut off (flashing amber indicating low voltage), and at times it will go into what the Niehoff troubleshooting refers to as "OVCO" or Over Voltage Cut Off (flashing red on the 28v LED). After...

"Electronic" or simply "Electric" ? Big differences.

Out of curiosity (and frustration with my Niehoff :rolleyes: ) - what bad things have you all heard about this double-alt.com offering? I don't see the point in replicating the dual voltage alt situation - but having two 24v alts (and using a 24/12 converter on one side) in a single unit for...
